VALVE.

Specification of Letters Patent. Patented June 10, 1919.

Application filed July 7, 191?. Serial No. 179,197.

To all whom it may concern:

Be it known that I, WILLIAM J. BROWN, a citizen of the United States,residing at Macon, in the county of Bibb and State of Georgia, haveinvented certain new and useful Improvements in Valves, of which thefollowing is a specification.

This invention relates in general to valves, and particularly to animproved construction of what is known in the trade as a stop and waste.

As heretofore practised, a stop and waste which is employed to cut offthe water from the service pipe, and, at the same time, drain theplumbing fixtures, is never provided with means to prevent water frombacking up through the waste opening, should for any reason the end ofthe waste opening become submerged. The present invention has for itsobject to overcome this condition and to so construct the device that itwill be impossible for the water to reenter the plumbing fixtures.

A further object is to incorporate the invention in a conventional typeof stop and waste in a simple and cheap manner.

With these and minor objects, the invention will be more readilyunderstood upon reference to the accompanying drawings, in which Figure1 is an end view of a stop and waste with the invention applied thereto;

Fig. 2 is a side view of a stop and waste with the invention appliedthereto; and

Fig. 3 is an enlarged detail view in section of the waste outletillustrating the detail construction of thecheck valve.

Referring to the drawings in detail, 1 represents the combined stop andwaste which is constructed in the usual manner with a service inlet 2, aplug 3 having the usual service opening therethrough and a waste.opening 4 which communicates, when the valve stem is turned in 01fposition, with the service opening which in turn communicates with theoutlet 5 in the side of the, I

casing of the stop and waste. 6 represents. the inlet connection to theplumbing fixtures.

Copies of this patent may be obtained for five cents It is to beunderstood that no novelty resides in the construction 'of the stop andwaste per 8c; it operates in a conventional manner, such as follows:When it is on, the waste opening in the stem will be out off,

through means of the side of the casing, but

this opening and the outlet 5. In most instances it is desirable toextend the waste outlet beyond the side of the casing through means of asmalltube, such as 7. Should for any reason the end of this tube 7become submerged, water wouidbe very likely to back up through the tubeand the waste outlet 5 into the plumbing fixtures. To prevent this, itis proposed by the present invention to employ a check valve 8 whichwill permit the waste water to be readily discharged, but prevent thesame from entering the plumbing fixtures. This check valve embodies aseat 9 for a ball 10, the seat 9 being provided with a threaded outerportion over which is threaded a retaining cap 11 having an opening 12.A strip of gauze or the like 13 is employed to prevent sediment fromentering the valve seat through the opening 12 and defeat the purpose ofthe ball, that is to say, prevent the sediment from getting between thevalve and its seat which would seating.

I claim An attachment for drain valves, compris ing a waste outlethaving a discharge terminating in an upwardly presented end above thevalve casing, and a check valve in said upwardly presented end. adaptedto permit the drainage from said valve through said outlet but closesaid outlet to back-flow from an outside source.

The foregoing specification signed at Ma: con, Georgia, this 28 day ofJune 1917.
